Answer
Therefore the final temperature is 23.92$^{\circ}$
Work Step by Step
We will use the equation $q=mc\Delta t$
q = heat transferred
m = mass
c = specific heat
$\Delta t $ = change in temperature
plug in the values.
345000 = (45000) (4.2) ($\Delta t $)
***We multiply 45000 times 4.2 and then divide 345000 by that answer
*** solve using a calculator
$ \Delta t = 1.82 ^{\circ} $
Therefore the temperature change is $1.82^{\circ}$
The initial temp is 22.1 so the final temp= initial temp + $ \Delta t$
= 22.1 + 1.82 = 23.92
Therefore the final temperature is 23.92$^{\circ}$
